Identification of Root-Associated Bacteria That Influence Plant Physiology, Increase Seed Germination, or Promote Growth of the Christmas Tree Species Abies nordmanniana

Abstract Fraser fir [Abies fraseri (Pursh) Poir.], the most important Christmas tree species in North Carolina, is rapidly gaining popularity nationwide. It is propagated by seed, but special needs such as genetic improvement will involve use of grafting, air layering, propagation by stem cuttings, and micropropagation (tissue culture). This paper summarizes research conducted to date on Fraser fir concerning these techniques in addition to information regarding seed production and sexual propagation.

Christmas Tree Species

A survey was developed evaluating the preference of consumers for purchasing three alternative Christmas tree species. Trees included: Pinus virginiana, a traditional Alabama Christmas tree; a containerized Ilex × `Nellie R. Stevens'; and a cut × Cupressocyparis leylandii. Virginia pine and leyland cypress were rated higher than the holly. The average rating on a scale of 1 to 5 for the Virginia pine and the leyland cypress was 3.75 and 3.63, respectively. Consumers rated the holly an average of 3.29. A rating of 1 indicated a strong negative response and a rating of 5 offered a strong positive response for buying the tree. The median rating for all three species was 4, indicating that 50% of the participants rated them a 4 or higher. The mode, or most frequent rating, was 5 for all three species. Although the average rating for the holly was lower than the average for the Virginia pine and leyland cypress, the holly and the leyland cypress may have a market niche with >50% of the respondents indicating that they would purchase the trees.

Several floral and tree preservatives were evaluated to determine their effect on postharvest needle retention of Fraser fir [Abies fraseri (Pursh) Poir.], an important Christmas tree species. Clorox (sodium hypochlorite) and aspirin (salicylic acid) caused massive needle loss, and three of the six commercial additives increased needle loss significantly, No treatment was better than water alone.

Abstract Luiz Fernando Gouvêa Labouriau (1921–1996) was a pioneer plant biologist who made significant contributions to plant physiology, mostly by bringing seed germination into a thermobiological context. His studies have set the foundations of seed science in Brazil and keep inspiring researchers until now.

Detailed study on seed storage and germination trailed in Knema attenuata (Wall. ex Hook. f. & Thomson) Warb.– the IUCN Red Listed ‘least concern’ medicinal tree species revealed that seeds were of recalcitrant nature. Viability of the seeds could be maintained for a longer period of up to 6 months with 47% Moisture content (mc) when kept in closed polycarbonate bottles at seed bank condition [20±20C Temp. and 40% Relative Humidity (RH)]. The 55% seed germination under normal climatic condition could be enhanced to a much higher percentage (75±5) inside the mist house chamber (34±30C Temp. and 70-80% RH).
